One million

Write the million number (1000000) by using only 9 numbers and algebraic operations plus, minus, times, divided, powers, and squares. Find at least three different solutions.

Result

a =  1000000
b =  1000000
c =  1000000

Solution:

a=999999+9/9=1000000=1.000000⋅106a=999999+9/9=1000000=1.000000\cdot 10^{ 6 }
b=99999⋅ (9+9/9)+99/9−9/9=1000000=1.000000⋅106b=99999 \cdot \ (9+9/9) + 99/9-9/9=1000000=1.000000\cdot 10^{ 6 }
c=(9+9/9)(9+9+9+9+9+9)/9=1000000=1.000000⋅106c=(9+9/9)^{ (9+9+9+9+9+9)/9 }=1000000=1.000000\cdot 10^{ 6 }
